Walter SST+ Cobalt Stub Drill Bit, Wire Gauge #22, Heavy Duty

Reliable Cobalt Drill Bits for Fabricators

For professional welders and fabricators, a broken drill bit isn't just an annoyance—it's a delay that costs money. The Walter #22 SST Stub Drill Bit is designed to solve the common frustrations associated with drilling hard metals. Built with a heavy-duty cobalt blend, this bit is specifically formulated to withstand the high heat generated when drilling through stainless steel, a common challenge in welding shops. The cobalt content ensures the cutting edges remain sharp long after standard high-speed steel bits have failed.

The "stub" design is a game-changer for sheet metal work and tight spaces. Because the bit is shorter than a standard length drill, it is incredibly stiff. This rigidity allows you to apply the necessary feed pressure to cut through hardened materials without the bit flexing or snapping. This is especially beneficial when using hand drills, where maintaining a perfectly perpendicular angle is difficult; the SST Stub Drill is forgiving and tough, resisting breakage even under less-than-perfect conditions.

Speed and efficiency are critical in the shop. That is why Walter has equipped this bit with a heavy-duty split point. This feature allows the bit to bite into the metal the instant you pull the trigger, eliminating the need for a center punch and preventing the bit from skating across your workpiece. This is ideal for drilling out spot welds or creating rivet holes in body panels and enclosures.

Additionally, the exclusive Bronze SST surface treatment helps the bit run cooler and eject chips more efficiently. This prevents the buildup of heat that can work-harden stainless steel, making your job easier and extending the life of the tool. When you need a hole drilled accurately and quickly, reach for the Walter SST Stub Drill. It is the durable, high-performance partner your welding projects demand.
